Most of these systems rely on the matching of fingerprints using the position and orientation of ridge endings and bifurcations within the fingerprint image,while this information is sufficient for matching fingerprints in small databases,it is not discriminatory enough to provide good results on large collections of fingerprint images.

The extracted objects with different ranges usually have different di stribution of gray scale value, due to uneven distribution of light and various properties of the crack background of fingerprints.
